Title: Improvements in and relating to magnetostrictive oscillators
IPC: H03B5/40
Filed: 1933-01-30
Abstract: 413,762. Sound-transmitting devices. WOOD, A. B., SMITH, F. D., Research Laboratory, Teddington, Middlesex, and DRYSDALE, C. V., Research & Experiment Department, Admiralty, London. Jan. 30, 1933, No. 2836. [Class 40 (iv).] An under-water sound oscillator of the magnetostrictive type is formed from magnetostrictive material in finely divided form treated so that the particles will be insulated from one another when in juxtaposition. The material, such as nickel, nickel alloy or cobalt alloy, can be in the form of powder, dust or small fragments having an exterior film of insulating material, the particles being consolidated into a solid block. Alternatively the finely divided material may be disseminated throughout a suitable insulating mass, preferably of the thermoplastic kind, the whole being moulded under heat and any desired pressure. An outer envelope may be applied either during the moulding process or subsequently thereto. According to a further modification, the finely divided material is sprayed on to a thin sheet of insulating material, the film so produced being painted or sprayed with a thin coating of insulating material and these processes repeated with or without the addition of thin interleaved sheets of insulating material until a slab or disc of the required thickness is built up. If desired, the finely divided and insulating materials may be sprayed simultaneously. Instead of coating the finely divided magnetostrictive material with insulating material, the former may be subjected to surface oxidation, the oxidized particles being consolidated to form a core which may be provided with an outer envelope. An enhanced magnetostrictive effect may be obtained by using a ferromagnetic dust in which particles are single crystals or portions of a single crystal, a strong magnetic field being applied when the material is in its unconsolidated state and maintained throughout the process of consolidation so as to orientate the particles in a preferred direction in which they are maintained until they are fixed in position by consolidation. If desired, the current windings may be placed in position inside the core before consolidation. The finely divided material may in some cases be brought into a magnetically soft condition by heat treatment before consolidation. Specifications 313,031, [Class 37], 314,891, [Class 40 (iv)], and 375,375 are referred to.

Title: Gas separation in hydrocarbon synthesis
IPC: C07C1/04
Filed: 1949-02-02
Abstract: In a process for producing a gas containing carbon monoxide and hydrogen in synthesis proportions in a synthesis gas generation zone and reacting the same in a catalytic synthesis zone, the reaction product is scrubbed with a solvent for carbon dioxide, and the solution stripped with a gas consisting of one or more of the components used in the feed for either the synthesis zone or the gas generation zone, at least part of the stripping gas containing stripped carbon dioxide being passed to said synthesis zone or gas generation zone.  Natural gas may be oxidized with oxygen or a metal oxide and the product passed to a stripping tower down which carbon dioxide-rich liquid, e.g. triethanolamine, flows.  The pressure preferably approximates that in the synthesis reactor.  The enriched synthesis gas passes to a synthesis reactor containing fluidized iron or cobalt catalyst.  The product is separated into gases and liquids, tail gas being scrubbed with carbon dioxide absorbent and, if desired, recycled.  The enriched absorbent is circulated to the stripper.  Alternatively, natural gas may be passed into the stripper and the effuent gas passed to a reformer where conversion with steam to carbon monoxide and hydrogen occurs.  The gases pass to a synthesizer, tail gas being treated with absorbent solution which is then passed to the stripper.  Flue gas from the reformer may be scrubbed with the absorbent solution and the solution passed to the same stripper. The evolved CO2 passes to the reformer.  The stripping gas or solution to be stripped may be preheated, for example with flue p  gas.

Title: Improvements in and relating to systems of heating feed water and the like
IPC: F22D3/00
Filed: 1925-02-02
Abstract: 228,573. International General Electric Co., Inc. Feb. 2, 1924, [Convention date]. Addition to 224,545. Feed-water, heating.-In apparatus for heating water according to the method described in the parent Specification, the heater is arranged outside the collector and the water of condensation is circulated by a pump or the like from the collector through the heater and back to the collector. Water from the condenser of a turbine 12 is pumped into a collector 1, from which it is withdrawn and circulated by a pump 7 through a heater 8 supplied with exhaust steam from an auxiliary turbine 11. The heated water is collected in a tank 2 and is re-circulated through the heater. When the water reaches the desired temperature, a valve 5 controlled by a regulator influenced by the water temperature or by the back pressure of the auxiliary turbine is operated to allow the heated water to flow into the boiler feed tank 3. When the tank 2 is empty, a float 9 so operates a valve 4 that the pump 7 withdraws water from the collector instead of from the tank 2. The float may also at the same time so operate a valve 6 in the exhaust pipe that the exhaust is taken back to a lower stage of the main turbine or to a condenser. As the steam pressure in the heater and the temperature of the outlet water fall, the valve 5 is so operated as to place the collector again into communication with the tank 2. A float 10 in the collector is so connected to the pump 7 that the pump is cut out when the collector is empty. When the tank is full, the float 9 reverses the valve 4 into a position to allow circulation of the water from the tank, and also so operates the valve 6 to allow the exhaust to flow into the heater again. The volume of the exhaust steam used for heating may be kept constant or not allowed to exceed a certain limit.

Abstract: 955,518. Jet propulsion plant. NORD-AVIATION SOCIETE NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. Jan. 26, 1962 [Jan. 27, 1961], No. 3137/62. Heading F1J. [Also in Division B7] A gas-turbine engine comprises low and high pressure, compressors 4, 2 driven by low and high pressure turbines 3, 1, respectively, and has a by-pass duct 18, feeding air to a nozzle 8 in common with the turbine exhaust gases. A further passage 12 normally feeds an annular passage 11 forming a ram jet engine having an annular intake 10, combustion equipment 13, and nozzle 14. For thrust reversal (the position shown) the intake 10 is closed by flaps 15, and passage 11 is closed by flaps 17, some of which at the same time open apertures 16 in the engine casing 9, through which air from passage 12 flows with a forward velocity component. Flaps 19 also close the by-pass duct 18. The effective nozzle outlet area of the turbine exhaust gases is now that of nozzle 14, instead of that of nozzle 8. This results in a decrease of the mass flow and velocity of the turbine exhaust gases, and increased flow through the apertures 16, with consequent increase in the nett reverse thrust. A modified flap 17 is described, Fig. 4, (not shown), which is returned to its forward thrust position by the pressure on its surfaces if its operating mechanism fails. The flaps 15 alone may be moved to the full line position, whereby the engine becomes a gas turbine with two by-pass ducts, with afterburning in one duct.

Title: A dual fuel cycle for two nuclear reactors
IPC: G21C1/00
Filed: 1965-01-27
Abstract: 1,045,003. Nuclear reactors; processing nuclear fuel. CANADIAN GENERAL ELECTRIC CO. Ltd. Jan. 27, 1965 [March 28, 1964], No. 3563/65. Headings G6C and G6R. The burn-up range of nuclear fuel is extended by first utilizing it in one type of reactor and then utilizing it further in another type of reactor. When enriched uranium has been burned in a reactor such as a light water moderated, an organic moderated or certain types of graphite moderated reactor to the burn-up level considered normal for depleted fuel for that particular reactor, its fissile content is slightly above that for natural uranium. Fuel discharged from such a reactor may be utilized directly in a natural uranium reactor, such as a heavy water moderated, a beryllium moderated or certain types of graphite moderated reactor. The fuel can be transferred directly from one reactor to the other, or before use in the second reactor it can be re-processed in one of the following ways: (i) the jackets containing the fissile material can be punctured, the fission product gases vented, and the punctures sealed; (ii) the jackets can be removed, the fissile material crushed and compacted into new shapes, and the new shapes reclad; (iii) individual fuel rods or other fuel shapes in an assembly or bundle can be regrouped in arrangements more suitable for use in natural uranium reactors. Natural uranium contains 0À7115% by weight U-235 and the enriched uranium referred to above contains from 0À7115 to 5% by weight U-235, or the equivalent in one or more of the following: U-233, Pu-239, Pu-241. Depleted fuel discharged from an enriched reactor has a U-235/Pu content above the equivalent fissile content of natural uranium and therefore provides for a natural uranium reactor reactivity above that available from natural uranium. This is accommodated in the operation of the natural uranium reactor by proper adjustment of the reactivity control mechanism. The enriched uranium fuel may be in the metal, oxide, carbide or nitride forms and the individual pieces have shapes such as rods, plates or spheres. A number of these pieces are sealed inside a thin-walled container made of zirconium alloy, aluminium, stainless steel, or other metal or alloy of low neutron captive cross-section. When, after discharge from the reactor, the containers are punctured, venting can be effected under atmospheric conditions or be accelerated by heating to release gases entrained in the solid fuel medium, or the gases can be more thoroughly exhausted by means of differential pressure, preferably with heat added. If the elements are to be declad, this may be done by piercing the sheaths and then applying a chemical to the fuel to cause swelling so as to break away the sheaths, e.g. UO2 is converted chemically to U3O8. The fission products are then removed and the U3O8 converted back into UO2 or into the nitride, the carbide, or the carbide dispersed in graphite.
